Full title and description

IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces — establishes technical requirements and test specifications for interconnection, performance, interoperability and testing of distributed energy resources (DER) with electric power systems (EPS).

Abstract

IEEE Std 1547-2018 is a comprehensive revision of the original 1547-2003 interconnection standard. It defines performance, operation, testing, safety considerations and maintenance requirements for DER interconnection, including responses to abnormal conditions, power quality, anti-islanding, voltage and frequency ride-through, reactive power and communications/interoperability expectations. The revision added explicit interoperability and information-exchange provisions and expanded test and verification requirements.

General information

• Status: Active standard.
• Publication date: Published April 6, 2018 (Board approval 15 February 2018).
• Publisher: IEEE Standards Association (IEEE).
• ICS / categories: Power systems / distributed generation / power stations (commonly indexed under ICS 27.100).
• Edition / version: IEEE Std 1547-2018 (revision of IEEE Std 1547-2003); later amended by 1547a-2020.
• Number of pages: Revision contains multiple clauses and annexes comprising approximately 136 pages (vendors and distributors sometimes list minor variations in page counts for packaged/pdf products).

Scope

Specifies technical criteria and requirements for interconnecting DER (including inverters, synchronous and induction machines) to distribution-level EPS at typical primary and secondary voltages. The standard addresses functional performance, response to area EPS abnormal conditions, power quality limits, anti-islanding, ride-through capabilities, voltage/frequency control and coordination, interoperability/communications interfaces, and test procedures needed for design, production, commissioning and periodic verification. The emphasis is on radial distribution systems while also considering networked distribution topologies.

Key topics and requirements

• Functional performance requirements for DER during normal and abnormal grid conditions (ride-through, trip settings, response categories).
• Voltage and frequency response: defined capability for active/reactive power control and frequency-voltage ride-through behavior.
• Anti-islanding and intentional islanding considerations plus coordination with protection systems.
• Power quality limits including harmonic injection, unbalance and flicker requirements.
• Interoperability and information exchange: standardized communication interfaces and information models to support grid support functions and utility integration.
• Test and verification requirements (type, production, commissioning and periodic tests) to demonstrate conformance with the standard.

Typical use and users

Used by utilities, distribution planners, interconnection engineers, DER manufacturers (inverter and generator vendors), testing laboratories, certification bodies, integrators, regulators and consultants to define, test and certify interconnection behavior and grid-support functions for solar, storage, combined heat and power and other distributed energy resources. It informs utility interconnection requirements, grid-code updates and product certification pathways.

Related standards

Key related documents and certification references include the superseded IEEE Std 1547-2003, the amendment IEEE Std 1547a-2020, IEEE Std 1547.1 (conformance test procedures, 2020 edition), and product safety/certification standards such as UL 1741 (including Supplement SB) which have been harmonized to reference IEEE 1547-2018 and 1547.1 test methods. Other regional grid codes and communications standards (for example protocols referenced for interoperability) are commonly considered alongside IEEE 1547.

FAQ

Q: What is this standard?

A: IEEE Std 1547-2018 is the IEEE standard that defines technical requirements, performance criteria and test specifications for interconnecting distributed energy resources with electric power systems.

Q: What does it cover?

A: It covers performance during normal and abnormal conditions (voltage/frequency), anti-islanding, power quality limits, reactive power/voltage control, interoperability/communications expectations, and the associated testing and verification requirements needed to demonstrate compliance.

Q: Who typically uses it?

A: Utilities, DER manufacturers, testing labs and certification bodies, system integrators, regulators and consultants use the standard to specify, test and approve DER interconnections and advanced grid-support functionality.

Q: Is it current or superseded?

A: As of its publication it revised and superseded IEEE Std 1547-2003; the 2018 edition remains active and was later accompanied by amendment 1547a-2020 and related conformance test procedures (IEEE 1547.1-2020). Users should verify if newer amendments or revisions have been published since 2018 for their jurisdiction.

Q: Is it part of a series?

A: Yes — IEEE 1547 is part of a family of standards, amendments and test-procedure documents (for example IEEE 1547.1 for conformance testing and 1547a amendment) plus related industry and certification standards such as UL 1741 that together form the framework for DER interconnection and certification.

Q: What are the key keywords?

A: DER, interconnection, interoperability, smart inverter, ride-through, anti-islanding, power quality, reactive power, conformance testing.
